-- Biden To Lead Task Force On Gun Violence: Echoing earlier reports, The Associated Press writes that President Obama is "launching an administration-wide effort to curb gun violence, underscoring the growing political consensus over tightening gun restrictions following the horrific massacre at a Connecticut elementary school. Obama is tasking Vice President Joe Biden, a longtime gun control advocate, with spearheading the effort. In remarks from the White House on Wednesday, Obama will outline a process for pursuing policy changes following the school shooting, though he is not expected to call for specific measures."

The National Rifle Association, as we reported Tuesday, says it "is prepared to offer meaningful contributions to help make sure this never happens again" and plans to hold a news conference on Friday.

-- "Geneticist Asked To Join Search For Clues." The Hartford Courant reports that "as detectives continue to comb through evidence and talk to people who witnessed Friday's mass murder at Sandy Hook Elementary School, the state's chief medical examiner is seeking clues in the gunman's biology. Dr. H. Wayne Carver has asked a geneticist at the University of Connecticut to join in his investigation of the killings. Carver is awaiting toxicology testing results for gunman Adam Lanza, 20, and information that may help answer the question of why Lanza gunned down 20 first-graders and six women at Sandy Hook."

Authorities say it appears Lanza also killed his mother, Nancy Lanza, before the school attack. Adam Lanza was found dead inside the school, from what authorities say was a self-inflicted gunshot.
